A British man worked on bombs planted in Iraq that claimed the life of a US soldier, a court has heard.
Sergeant Randy Johnson, 34, was killed in an explosion near Baghdad in 2007, Woolwich Crown Court heard.
The fingerprints of Anis Abid Sardar, from Wembley, London, were allegedly found on two other bombs at the scene, but not that which killed Sgt Johnson.
Mr Sardar, 38, denies murder, conspiracy to murder and conspiracy to cause an explosion.
Prosecutor Max Hill QC told the court: “This is an unusual trial in that almost all of the evidence you will see and hear comes from Iraq.
“The Crown’s case is that the defendant Mr Sardar was directly involved in making bombs for use in Iraq during 2007.
